El Hierro volcano (Canaries): Increase in small earthquakes

February 16, 2012 - The submarine eruption south of El Hierro Island could be in a process of modify: Even though obvious activity on the sea surface area over the vent, as properly as harmonic tremor signal (thought to be far more or much less proportional to erupting magma flux) have virtually ceased, the number of earthquakes below the island has enhanced sharply since yesterday.

On fifteen February, more than twenty quakes were measured. Most of the earthquakes have been very small, effectively below magnitude 2, and had been clustered beneath the NW and SW sectors of the island at depths of about 10 km.

There is no conclusive interpretation of this measurement.
